Description

Technical Field

[0001] This utility model relates to the field of tunnel monitoring technology, specifically to a traffic tunnel monitoring device. Background Technology

[0002] Tunnels, as special traffic scenarios that are either enclosed or semi-enclosed, present challenges such as poor visibility, weak ventilation, difficult evacuation, and complex structural loads. Monitoring devices primarily address three core needs: real-time monitoring of traffic flow, accidents, and fires to provide early warnings and guide rescue efforts; monitoring deformation and cracks in the tunnel structure (such as lining, roof, and road surface) to prevent structural safety accidents like collapses; and optimizing traffic management through data (such as lane guidance and speed limit adjustments) to reduce congestion, and intelligently starting and stopping auxiliary equipment (such as ventilation and lighting).

[0003] After prolonged use, dust can obstruct the view of current traffic tunnel monitoring devices, causing blurry or lost video footage and affecting real-time monitoring of traffic conditions within the tunnel. Some devices require ladders to be used for dust removal, which is very laborious and inefficient because the monitoring cameras are generally installed at a high position. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A traffic tunnel monitoring device, comprising:

[0006] Mounting frame, with the monitoring instrument body rotatably connected to the top of the mounting frame, and a fixing frame fixedly connected to the bottom of the monitoring instrument body, and a negative pressure dust collection mechanism provided on the inner side of the fixing frame;

[0007] A fixing plate is fixedly connected to the bottom of the monitoring instrument body, a protective cover is fixedly connected to the front side of the fixing plate, a negative pressure cover is slidably connected inside the protective cover, four fan-shaped holes are opened circumferentially on the right side of the negative pressure cover, a bearing is fixedly connected to the middle position on the right side of the negative pressure cover, and a cleaning mechanism is provided inside the bearing.

[0008] A second through hole is provided on the left side of the negative pressure hood, and a second flexible hose is fixedly connected to the outside of the negative pressure hood near the second through hole. One end of the second flexible hose is fixedly connected to the negative pressure dust collection mechanism.

[0009] In one possible implementation, the negative pressure dust collection mechanism includes a dust collection box, a sealing plate is fixedly connected to the front side of the dust collection box by a bolt connection pair, and a first through hole is opened on both the left and right sides of the dust collection box. The first through hole on the left side is fixedly connected to a second flexible hose, and a first flexible hose is connected to the right side of the dust collection box near the first through hole. One end of the first flexible hose is connected to a negative pressure fan.

[0010] In one possible implementation, a filter screen is connected to the right side wall of the dust collection box near the first through hole.

[0011] In one possible implementation, the cleaning mechanism includes a shaft with a motor connected to one end, one side of the motor being fixedly connected to the right sidewall of the negative pressure shroud, and a back plate connected to the other end of the shaft, with a lens cleaning brush connected to the front side of the back plate.

[0012] In one possible implementation, the positions of the motor and the second through holes are staggered.

[0013] In one possible implementation, electric push rods are connected to both the left and right sides of the protective cover, and one end of the output shaft of the electric push rod is connected to a fixing lug, the inner side of which is fixedly connected to the negative pressure cover.

[0014] In one possible implementation, the front side of the negative pressure cover is connected to a rubber sealing ring on the outside of the four fan-shaped holes.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By activating the electric push rods on both sides, the negative pressure cover is lifted from inside the protective cover to the height of the camera lens. The rubber sealing ring on the front of the negative pressure cover helps to improve the sealing effect between the negative pressure cover and the camera lens. Then, the motor is turned on to drive the back plate and lens cleaning brush to rotate, which facilitates the cleaning of dust on the camera lens. At the same time, the negative pressure fan is turned on to create negative pressure inside the negative pressure cover, which facilitates the suction of dust from the lens through the second hose into the dust collection box. The dust is then trapped and collected by the filter screen in the dust collection box. No manual climbing is required, which greatly shortens the cleaning time and improves the cleaning efficiency.

[0017] 2. By installing a protective cover at the bottom of the monitor body, the negative pressure cover can be easily stored when dust cleaning is not required, thus preventing it from affecting the monitoring effect. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This application provides a traffic tunnel monitoring device to solve the problems in the prior art.

[0028] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0029] like Figures 1-5 As shown, a traffic tunnel monitoring device includes:

[0030] Mounting bracket 1, with the monitoring instrument body 10 rotatably connected to the top of the mounting bracket 1, and the fixing bracket 5 fixedly connected to the bottom of the monitoring instrument body 10, with a negative pressure dust collection mechanism provided on the inner side of the fixing bracket 5.

[0031] A fixing plate 11 is fixedly connected to the bottom of the monitoring instrument body 10. A protective cover 7 is fixedly connected to the front side of the fixing plate 11. A negative pressure cover 9 is slidably connected inside the protective cover 7. Four fan-shaped holes 13 are opened circumferentially on the right side of the negative pressure cover 9. A bearing 15 is fixedly connected to the middle position on the right side of the negative pressure cover 9. A cleaning mechanism is provided inside the bearing 15.

[0032] A second through hole 23 is provided on the left side of the negative pressure hood 9. A second flexible hose 8 is fixedly connected to the outside of the negative pressure hood 9 near the second through hole 23. One end of the second flexible hose 8 is fixedly connected to the negative pressure dust collection mechanism.

[0033] In some examples, the negative pressure dust collection mechanism includes a dust collection box 4. A sealing plate 12 is fixedly connected to the front of the dust collection box 4 by a bolt connection. First through holes 21 are provided on both the left and right sides of the dust collection box 4. The first through hole 21 on the left side is fixedly connected to a second flexible hose 8. A first flexible hose 3 is connected to the right side of the dust collection box 4 near the first through hole 21. One end of the first flexible hose 3 is connected to a negative pressure fan 2. After the negative pressure fan 2 is started, it will continuously draw air from the inside of the dust collection box 4 through the first flexible hose 3 to form a stable low-pressure environment (negative pressure) inside the dust collection box 4. The airflow is directional and guided. The first through hole 21 on the left side of the dust collection box is connected to the second flexible hose 8. The other end of the second flexible hose 8 corresponds to the negative pressure cover 9. When a negative pressure is formed inside the dust collection box 4, it will generate suction in the direction of the negative pressure cover 9 through the second flexible hose 8. The dust swept down from the lens will be drawn into the second flexible hose 8 by this directional airflow and finally enter the dust collection box 4.

[0034] In some examples, a filter 22 is connected to the right side wall of the dust collection box 4 near the first through hole 21. By setting the filter 22, it is convenient to intercept and collect dust.

[0035] In some examples, the cleaning mechanism includes a shaft 20, one end of which is connected to a motor 19. One side of the motor 19 is fixedly connected to the right side wall of the negative pressure cover 9. The other end of the shaft 20 is connected to a back plate 18. A lens cleaning brush 17 is connected to the front side of the back plate 18. When the motor 19 is turned on, the back plate 18 and the lens cleaning brush 17 are driven to rotate, which facilitates the cleaning of dust on the lens of the camera.

[0036] In some examples, the positions of the motor 19 and the second through hole 23 are staggered to facilitate the motor 19 blocking the negative pressure airflow of the second through hole 23 during negative pressure vacuuming.

[0037] In some examples, electric push rods 6 are connected to both the left and right sides of the protective cover 7. One end of the output shaft of the electric push rod 6 is connected to a fixing ear 14. The inner side of the fixing ear 14 is fixedly connected to the negative pressure cover 9. Opening the electric push rods 6 on both sides drives the negative pressure cover 9 to be lifted from inside the protective cover 7 to the height of the camera lens. Conversely, it is convenient to retract the negative pressure cover 9 back into the protective cover 7.

[0038] In some examples, the front side of the negative pressure cover 9 is connected to a rubber sealing ring 16 on the outside of the four fan-shaped holes 13, which helps to improve the sealing effect between the negative pressure cover 9 and the camera lens.

[0039] This invention uses the electric push rods 6 on both sides to drive the negative pressure cover 9 to be raised from inside the protective cover 7 to the height of the camera lens. The rubber sealing ring 16 on the front of the negative pressure cover 9 helps to improve the sealing effect between the negative pressure cover 9 and the camera lens. Then, the motor 19 is turned on to drive the back plate 18 and the lens cleaning brush 17 to rotate, which facilitates the cleaning of dust on the camera lens. At the same time, the negative pressure fan 2 is turned on to create a negative pressure inside the negative pressure cover 9, which facilitates the suction of dust cleaned from the lens through the second hose 8 into the dust collection box 4. The dust is then trapped and collected by the filter 22 set in the dust collection box 4. When it is necessary to clean the dust in the dust collection box 4, the four bolts connecting the outer side of the sealing plate 12 can be removed to remove the sealing plate 12 for dust cleaning.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
